Effectiveness of a CD-ROM multimedia tutorial in transferring cognitive knowledge essential for laparoscopic skill training

BACKGROUND: Computer-assisted instruction (CAI) can benefit surgical educat ion by improving efficiency, effectiveness, standardization, and access. Th is study compares knowledge gains for laparoscopic skill acquisition follow ing a standardized tutorial delivered via CD-ROM versus live instructor. METHODS: A standardized tutorial was written and subsequently converted to multimedia CD-ROM format by its author (JR). During a laparoscopic developm ent course, experienced US-trained surgeons (n = 52) participated in the tu torial delivered live by the author. The CD-ROM tutorial replaced the instr uctor for the following groups: (1) experienced US-trained surgeons (n = 27 ); (2) US-trained surgical residents (n = 59); and (3) Greek surgeons (n = 63). A 51-item knowledge test was administered before and after tutorial in struction. RESULTS: The mean increase in scores between pretest and posttest was signi ficant (P <0.01) and of similar magnitude in each group, with nonsignifican t posttest mean differences among US-trained groups. CONCLUSIONS: The CD-ROM tutorial effectively transfers cognitive informatio n necessary for skill development. Distance learning modes of this tutorial program may be feasible.
